thanks Scoff, ARP are now doing stud kits for them, and was principally looking for the GTA PRV6 as you no doubt guessed, but need a 1.25 M12 ... shall keep looking :coffee:

Yes, guessed what you were doing :)

Are you sure that standard bolts will not suffice ?

We're having to reuse turbo head bolts so are on the lookout for an alternative .Only the Atmo bolts are out there new and they are only 8.8 .
M12 x 1.5 x 180 .
It may be that 16v Intergrale will do the job ,Mr F is checking ......
